異型齒輪也稱為非圓齒輪。分度曲面是非旋轉曲面的齒輪，與另一個齒輪組成齒輪對后，在嚙合過程中瞬時角速度比以一定的運動規則變化。iHF合發齒輪加工廠家加工生產定做異型齒輪，精度高、價格低、交期快。

由于異形(xing)(xing)(xing)齒(chi)(chi)(chi)輪種類繁多，形(xing)(xing)(xing)狀復(fu)雜，給制造帶來一定的困(kun)難(nan)。加(jia)工異形(xing)(xing)(xing)齒(chi)(chi)(chi)輪有很多方(fang)法(fa)。根據齒(chi)(chi)(chi)形(xing)(xing)(xing)形(xing)(xing)(xing)成(cheng)(cheng)的原理，有成(cheng)(cheng)形(xing)(xing)(xing)法(fa)和生成(cheng)(cheng)法(fa)。從加(jia)工方(fang)法(fa)上分為銑齒(chi)(chi)(chi)、開槽(cao)齒(chi)(chi)(chi)、滾(gun)(gun)齒(chi)(chi)(chi)和線切割(ge)。當(dang)今(jin)運用(yong)(yong)最廣的是(shi)在數(shu)(shu)控機床插(cha)齒(chi)(chi)(chi)機上，用(yong)(yong)規范(fan)的傳(chuan)動齒(chi)(chi)(chi)輪插(cha)刀(dao)生產加(jia)工，或在數(shu)(shu)控滾(gun)(gun)齒(chi)(chi)(chi)機上，用(yong)(yong)齒(chi)(chi)(chi)輪齒(chi)(chi)(chi)條形(xing)(xing)(xing)數(shu)(shu)控刀(dao)片(pian)或規范(fan)的傳(chuan)動齒(chi)(chi)(chi)輪滾(gun)(gun)刀(dao)生產加(jia)工。
